Helping Founders Turn Signups Into Customers

PostSignup started from a simple frustration: as founders ourselves, we spent hours manually following up with every new signup. We tried the big email marketing tools, but they were built for marketers sending newsletters, not founders having conversations.

We needed something different. Something that would send emails that looked like they came directly from us — because the best follow-up emails don't look like marketing. They look like a founder reaching out personally.

So we built PostSignup. A tool that connects to your real email (Gmail or Outlook), sends from your address, and makes every automated email feel like you wrote it yourself. Because you did — you just wrote it once.

Today, PostSignup helps hundreds of founders save time while building real relationships with their users. And we're just getting started.
